Project A requires an original investment of $50,000. The project will yield cash flows of $15,000 per year for 7 years. Project B has a computed net present value of $13,500 over a 4-year life. Project A could be sold at the end of 4 years for $25,000. (a) Using the present value tables that follow, determine the net present value of Project A over a 4-year life with salvage value assuming a minimum rate of return of 12%. (b) Which project provides the greatest net present value? Following is a table for the present value of $1 at compound interest:

Year	6%	10%	12%
1	0.943	0.909	0.893
2	0.890	0.826	0.797
3	0.840	0.751	0.712
4	0.792	0.683	0.636
5	0.747	0.621	0.567
